标准模型下基于身份代理签名方案的密码学分析
Cryptanalysis of an identity-based proxy signature scheme in the standard model
摘要
Abstract
The identity-based proxy signature scheme in standard model has been proposed the scheme is not as secure as what it claimed. By security analyzing, three insecurity factors are pointed out: a malicious original signer can forge any proxy signature of any user; a dishonest proxy signer is able to produce any proxy signature on behalf of arbitrary user; moreover, an external adversary is capable of forging any proxy signature on behalf of any message of any original signer and proxy signer. Using cryptography analysis methods, the security of that scheme is not strong as it claimed and it doesn't meet the strongly unforgeable requirements.关键词
